No, I expect them to use a greeting without baggage unless they know the people.
They are. The fact that you want to force baggage onto it is your problem. It's not reasonable to expect people to avoid saying 'goodbye' because the atheist might be an etymology buff, either.
Btw, has it ever occurred to you that you don't need to be Christian for a Christian to consider you blessed in that extremely hollow sense?
Is there a reason you're paying so little attention to this thread that you keep saying 'greeting' when the contested phrase is a farewell?
Courtesy is the act of trying to make those around you as comfortable as possible.
No, that would be hospitality. Courtesy is the thousand and one empty forms we follow to keep each other calm in the face of countless strangers, most of whom don't care if we exist, but any one of whom may well mean us harm. Saying please and thank you, holding doors for people behind you, pausing to let someone move through the same space you need to be in, well-wishing strangers or inquiring into their wellbeing
when we don't care at all... all the little things that we use to signal that we're
notlooking for a fight.
Using a phrase that goes against this goal is not courteous.
Well wishing doesn't go against the real goal. Creating conflict because someone else's courtesy doesn't conform to your religious affiliation absolutely does.
Gee, maybe the one you articulated perfectly, but abandoned when I pointed out that you're violating it?
The only sound principle here is the one you're violating: that we should consider the effects our words will have before we say them.
Odd, when you said it before, it was that we should NOT indulge in self-serving behavior that makes other people uncomfortable. Can you explain how creating conflict by insisting that a stranger's polite well-wishing is a personal attack on your freedom to believe as you wish is
anything else?
Real people have told you that phrases like "have a blessed day" affect them negatively, but you still insist that they're good to say. Why?
Real people say the same about any holiday good wishes other than "merry Christmas," and use all the same arguments you have here. Do you support them?
People can say anything affects them any way they please, but that alone is insufficient to justify that everyone else change to suit them.
Here, I'll show you: your refusal to be reasonable about such a trivial matter is negatively affecting me. Now, are you obligated to admit that it is completely trivial?
